Updates:

The bookmarklet doesn't work with versions of IE anterior to 6.x since
document.getElementsByTagName('*') isn't interpreted correctly. For IE
6.x and following, due to a limitation of the length of a bookmark URI
to 508 characters, you should use the shorten version below:
javascript:(function(){var i,n,a,j,l;b=document.getElementsByTagName('*');for(i=0;i<b.length;++i){a=b[i];if(a.id||(a.tagName=="A"&&a.name)){j=document.createElement("img");j.src="http://www.nimbustier.net/images/ancre.png";j.style.border="none";j.alt="";if(a.id){n=a.id;}else{n=a.name;};if(a.tagName!="A"){l=document.createElement("a");}else{l=a;};l.href="#"+n;l.appendChild(j);if(a.tagName!="A"){a.appendChild(l);};l.style.border="1px solid black";}}})();

[sorry for the long line, but that it should be easier to paste it
directly in your browser that way]
